ReadyLIFT Tubular SST Upper Control Arms for Lifted Chevy Silverado & GMC Sierra 1500

Correct severe suspension geometry angles and eliminate ball joint failure on lifted trucks with ReadyLIFT Heavy-Duty Tubular SST Upper Control Arms, specifically engineered for 2014–2018 GM 1500 trucks featuring 4-inch suspension lifts and factory cast aluminum or stamped steel control arms. According to chassis engineering evaluations conducted by SEMA, installing heavy-duty tubular control arms on lifted platforms restores proper caster and camber alignment parameters, preventing premature tire scrub and joint binding during suspension cycle extremes.

As chief suspension engineers state, "Heavy-wall DOM steel tubing combined with maintenance-free pivot bushings corrects upper ball joint operating angles, delivering quiet, noise-free performance and full wheel travel on lifted trucks." Built with heavy-duty greasable ball joints and high-strength TCT bushings, these control arms ensure long-term durability under demanding off-road conditions.
